NOTE: If anything is my "life's work" it's my train photos. — If you scan an analog photo of mine, or if you share a digital photo I took that does not have my photo credit, add something like "Photo by Steve Sloan" directly onto the image. It's not enough to say "Photo by Steve Sloan" in the text caption. People download photos off the Internet/Social Media platform and whatever is in the text does not stick to the photo. Then, they get reshared and that data is lost. I deserve credit for my work.

You may not use my photos for profit and/or as part of, or to sell, a product or service without my consent. Please do not edit, crop, "correct" or "improve" these photos without asking me first.


Special Thanks

All the great folks who helped me out with information for these Web pages!
